Influence of boron content on the fracture toughness and fatigue crack propagation kinetics of bainitic steels [PDF]

open access: yes, 2016
The relatively good combination of high strength and ductility makes bainitic steels a candidate to replace many other steels in industrial applications. However, in service, ductility and strength are not up to standard requirements.

Effect of the morphology of the martensite-austenite phase on fracture of the weld heat affected zone in vanadium and niobium microalloyed steels [PDF]

open access: yes, 2010
In multipass welding, the intercritically reheated coarse grained heat affected zone demonstrates the worst toughness in welded joint, since it contains a high-carbon martensite with some retained austenite, known as M-A phase, which is brittle and ...

A strong, ductile and in-plane tensile isotropic Mg-0.5Zn-0.5Y-0.15Si alloy

open access: yesJournal of Materials Research and Technology, 2022
Strength ductility tradeoff, strain hardenability and in-plane isotropy under tensile loading are big dilemmas in magnesium alloys. In this study, we have fabricated an extruded low alloyed Mg-0.5Zn-0.5Y-0.15Si alloy.

Vanadium Effect on a Medium Carbon Forging Steel

open access: yesMetals, 2016
In the present work the influence of vanadium on the hardenability and the bainitic transformation of a medium carbon steel is analyzed. While V in solid solution enhances the former, it hardly affects bainitic transformation.
